Will my SEO rankings be affected?

Done right, zero ranking loss, and usually a small lift from M2’s better Core Web Vitals. Our SEO continuity protocol: (1) Pre-migration Screaming Frog crawl captures every indexed URL + status code + title + meta + canonical + hreflang. (2) Every legacy URL gets a 301 redirect to its M2 equivalent (auto-mapped where slugs match, manual where they don’t). (3) Schema.org JSON-LD, hreflang, canonicals, meta robots, and XML sitemaps all carried over. (4) Post-launch crawl compares against pre-launch, any 4xx/5xx flagged and fixed within 24 hours. (5) Search Console resubmission of new sitemap. Most stores see ranking improve within 60 days from speed alone.
